I have had to do this several times and find that local application
of heat (or cold) is effective. A slow continuous heat source such
as heated sand bags is effective and simple to use. Alternatively
ice packages are an option but acrylic will become brittle if frozen
so the heat is better. I think there is a description of both hot
and cold methods in the 1994 Tate conference proceedings 'Modern
works, Modern problems'.
